Louver material and its manufacturing method, louver, opening and closing structure, and manufacturing method of interior exterior material with wooden grain pattern

摘要

Problem to be solved: to construct a louver so that it is possible to manufacture the louver material which demonstrates the visual effect of the wood at low cost, and to be able to see the natural feeling formed by the wood.Solution: a plurality of convex bars 28 extending along the direction of extrusion of the louver material 2 are disposed on an outer surface of a louver material 2 made of an aluminum material to which brown paint is applied.The plurality of convex bars CS disposed on the outer surface do not have a uniform size, and the projecting height of each of the plurality of convex muscles CS of the outer surface and the projecting muscles on both sides of the convex muscles differ from each other. A portion of the above described convex muscle and the projecting muscles on both sides of which are arranged at different positions are provided on the outer surface.Diagram
